John Alleman, the second spokesman for the Heart Attack Grill in two years to die suddenly, passed away at the age of 52.

Alleman went into cardiac arrest as he sat at a bus stop in front of the Las Vegas Boulevard restaurant last week and was taken off life support Monday afternoon.

The restaurant’s owner Jon Basso told the Las Vegas Sun that the 180 pound native of Pennsylvania “lived a very full life and will be missed”.

Basso said, “He lived, ate and breathed the Heart Attack Grill.”

The novelty restaurant features a medical theme complete with sexy nurses, features unhealthy items on their menu including Flatliner Fries and the 3-pound Quadruple Bypass Burger (almost 10,000 calories!).

The restaurant’s initial spokesman, 575-pound Blair River, died of flu-related pneumonia at the age of 29 in March 2011. Last year, a man was rushed to the hospital while eating the 6,000-calorie Triple Bypass Burger.

Basso, who will close the eatery the day of Alleman’s funeral, said the tragedy “isn’t going to stop us from what we’re doing. People have got to live their lives.”

John was dubbed, “Patient John” by the staff and regulars. He often ate at the burger joint and was so recognizable the restaurant made him the unofficial mascot.

Basso told the Las Vegas Sun, “I told him if you keep eating like this, it’s going to kill ya. He’d say, ‘I just love your place, Jon.’ He’s the only person I know who was probably at the restaurant more than I.”
